Half-Life | £1.49 | Steam | PC

Widely regarded by PC gamers to be one of the finest games ever made, this legendary FPS should at least be tried by all gamers, like some form of compulsory gaming history lesson. If you're playing it for the first time, expect it to have aged like your grandad's wardrobe, but there's no denying the huge influence the game had. The first half hour's a bit cack though - *get's ripped away from keyboard by other Dealspwn staff*
